SHADE-FRAM E.

SPEcIF'IcA'rIoN forming art of Letters Patent No. 632,120, dated August29, 1899.

Application filed March 9, 1899. Serial No. 708,397. (No model.)

of Bufialo, in the county of Erie and State of New York, have invented anew and Improved Shade-Frame, of which the following is a full, clear,and exact description.

The object of the invention is to provide a new and improvedshade-"frame more especially designed for use on electric lamps andwhich is simple and durable in construction, readily applied to a lampin any position, and arranged to securely hold the shade in place.

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claims.

A practical embodiment of my invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a side elevation of the improvement. Fig. 2 is an invertedplan view of the same. Fig. 3 is a sectional side'elevation of amodified form of the improvement, and Fig. 4 is a side elevation of thesame.

The improved shade-frame illustrated in Figs. 1 and 2 is provided with abeveled ring A, from the upper end of which extends an annular flange A,formed with an inwardlyextending short flange A both flanges A A beingformed with vertical slits, so as to render the parts formed therebysufficiently yielding to permit of readily passing the small end of theshade over said flanges to finally bring the shade in engagement withthe beveled ring A, so as to properly support the small end of the shadeon the frame. As is well known, shades are usually in the form of afrustum of a cone, the sides of which correspond to the bevel on thering A, the small diameter of the shade corresponding approximately tothe diameter of the small end of the ring A.

On the ring A are fastened, preferably by means of rivets B, a number ofspring-arms 0, having their upper ends G projecting beyond the flanges AA as is plainly shown in Fig. 1, to engage the socket of the lamp, as isplainly indicated in said Fig. 1. The lower end 0 of each spring-arm 0extends below the ring A and is preferably split into two arms 0 C ofwhich the arm C is curved inwardly and rests with its free end on thebulb of the lamp, as indicated in said Fig. 1. The

other arm 0 is formed at its outer end with an eye for receiving andsupporting a wire ring D, on which rests a portion of the shade betweenthe upper and lower ends thereof, as indicated in dotted lines inFig. 1. Each of the spring-arms O is riveted to the inside of the ringA, and the ends 0' C extend in alinement with each other and at an anglecorresponding to the bevel of the ring A. .Thus by the arrangementdescribed the shade is securely supported at the small end and at adistance therefrom, and as the frame is fitted centrally on the lamp itis evident that the shade is in a proper symmetrical position relativelyto the lamp. It is expressly understood that when the shade is inposition on the frame its upper edge abuts against the lower portion ofthe vertically disposed flange A, so that the shade is not liable toslip upward on the frame nor downward thereon owing to the conical formof the shade and ring.

The supporting-ring may be omitted, as shown in Figs. 3 and 4., and inthis case'eaeh spring-arm C has its upper end 0 similar in form to theupper end 0 of the arms 0, as shown in Fig. 1, while the lower end 0 isnot split, but is curved inwardly and rests directly on the bulb of theelectric lamp when the latter extends upward, as indicated in dottedlines in Fig. 4. The heads of the rivets B in this case also rest on thebulb, so as to hold the middle portion of the spring-arms, as well asthe ring, away from the bulb to allow a free circulation of air, andthereby prevent the frame from becoming und ulyheated. Otherwise thering A, on which the arms 0 are riveted, is the same as above describedin reference to Figs. 1 and 2, so that further description of the sameis not deemed necessary, it being understood, however, that the shadealso rests on the straight parts of the lower arms 0 of the spring-armsinstead of on the ring D to properly hold the shade in place.

From the foregoing it is evident that the frame can be readily attachedto a lamp no matter what position it is in-that is, whether it hangsdownward, extends upward, or at an angle-and the spring-arms alwaysserve to securely hold the frame in proper position on the lamp, andconsequently the shade is held in a corresponding position relative tothe position of thelamp.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. A shade-frame for electric lamps,comprising a beveled ring having an annular vertical flange cut to yieldsufliciently for the passage of the small end of the shade and for theedge of the shade to abut against, springarms secured to said beveledring for engaging the lamp, each springarm extending above and belowsaid ring, the lower end being split to form two arms, one of which iscurved inward to engage the bulb, and a ring FRANKLIN E.
